What Insects Are Biting You As You Sleep?
If you wake up with itchy red spots, you might be a victim of nighttime insect bites. Common culprits include bed bugs, mosquitoes, and fleas. Other possible pests are spiders, ticks, midges, and gnats, though they are less frequent offenders.

1. Bed Bugs
Bed bugs are tiny brown insects that feast on human blood and can infest your bed, furniture, and carpet. They are excellent at hiding and are most active at night. So, how do you know if bed bugs are the problem?
Signs of Bed Bug Infestation
If you are being bitten by bed bugs as you sleep, you’ll notice small red bumps on your skin, usually in a line or cluster. Additionally, you’ll see tiny dark spots on your mattress or bedding, which are their droppings.
How to Deal with Bed Bugs
To get rid of them, you’ll need to wash and dry all bedding and clothing in hot water. Bed bugs cannot survive high temperatures, so washing and drying all bedding and clothing in hot water (at least 130 degrees Fahrenheit) will kill any bed bugs that are present.
Clean and vacuum the infested area. Thoroughly vacuum the infested area, paying special attention to mattresses, box springs, bed frames, furniture, and any other areas where bed bugs may be hiding. Make sure to empty the vacuum bag immediately after use and seal it in a plastic bag.
If you are unable to get rid of the bed bugs yourself, you may need to call a pest control professional.
2. Mosquitoes
During warmer months, mosquitoes can be a real nuisance. Unlike bed bugs, mosquitoes fly and can enter your home through open windows or doors.
Telltale Signs of Mosquito Bites
These bites appear as swollen, red bumps and are often found on exposed areas like your arms and legs. They also itch—a lot!
Tips to Keep Mosquitoes Away
To deter these pests, use mosquito nets or screens on windows. Applying an insect repellent before sleep can also help keep them at bay.
3. Fleas
You may associate fleas with pets, but they also bite humans. Fleas can leap from your pet’s fur onto your bed or furniture.
Spotting Flea Bites
Flea bites resemble small, red bumps, but unlike bed bug bites, they usually form random patterns on your skin.
Handling a Flea Situation
For effective flea control, treat both your pet and your living environment. Vacuum your home frequently and consider using pet-safe flea treatments.
4. Midges
Midges may be small, but their bites can cause a lot of discomfort. They are usually found near water bodies and are active during dawn and dusk.
Identifying Midge Bites
Midge bites can cause red, itchy bumps, often appearing in clusters.
Keeping Midges Away
Avoid areas near water bodies during their active times and consider using repellent sprays designed for midges.
5. Gnats
Gnats are small flying insects that can also bite, especially the females. They are generally found in damp environments.
Signs of Gnat Bites
Gnat bites can cause skin irritation and small red bumps, similar to mosquito bites.
Tips for Gnat Prevention
To minimize gnat issues, eliminate standing water around your home and use insect repellent.
6. Spiders
Although spiders typically don’t bite humans unless threatened, some species can bite when they feel trapped.
When to Suspect a Spider Bite
A spider bite will generally cause localized pain and swelling. Some species can cause more severe symptoms, so consult a healthcare professional if you’re concerned.
Keeping Spiders at Bay
Make sure to shake out clothing and bedding that has been stored for a while. This will help to dislodge any hiding spiders.
7. Ticks
Ticks are more commonly encountered in wooded areas but can find their way into homes on pets or clothing.
Identifying Tick Bites
A tick bite can cause a small, red bump and may include a rash. Some ticks can transmit diseases, so consult a healthcare provider if you find a tick on your skin.
Preventing Tick Bites
If you’ve been outdoors, check your clothing and skin for ticks. Also, consider using a tick repellent when venturing into wooded areas.
